Flexible roof panel and dual-USB controller on a campervan
A customer sent photographs of the panel, the controller and the DC side, along with a note about how the system has performed.
Added:
The panel sits flat on the roof of the van, with a wind deflector ahead of it so the leading edge is not the first thing the air meets. Nothing is raised above the roof line, which matters on a vehicle that has to pass under things.
Inside, the controller is mounted on an interior panel with the battery alongside it, at a height where the display can be read without moving anything. The photograph was taken with the system live and the readout showing 12.8 V.
The DC side sits under a seat: an M5 terminal block, a red breaker and a voltage-sensitive relay, with the cabling run together rather than left loose across the compartment.
The system uses a ZT series solar charge controller and an SYGSP-F series flexible panel. The controller is the PWM unit with the dual USB outlets and dual solar inputs shown in the second photograph; the panel is the flexible type laid flat on the roof in the first. The customer reports both working well. The pages for the two series are linked below, followed by his own words.
In the customer's words
“I'm really liking both the controllers and the panels. I like the durable coating on the panels. It looks far better than the last ones I got, and the controller is excellent with dual USBs and dual solar inputs. I'll definitely be getting more from you when I need some!”
